[Click] dynamic reconfiguration

[Koen Beel]

Hi Hamza,

You can specify configuration parameters via a configuration string in
your click config file.
e.g.  FromDevice(eth0, PROMISC true)
If you write your own elements check for example the source of
FromDevice to see how to parse the configuration string. (method int
configure(Vector<String>, ErrorHandler))
[CLICKDIR/elements/linuxmodule/fromdevice.cc]

And if you want to reconfigure elements at runtime, you can use the
proclikefs in kernel mode. e.g. element Queue
http://www.read.cs.ucla.edu/click/elements/queue
This element has some handlers, some read-only, some read/write. If
you want to know the queue length just read (cat) 'length'. If you
want to set its capacity, write to 'capacity'.

Check section 'userdriver', 'linuxmodule' and 'language' at
http://www.read.cs.ucla.edu/click/docs for more info.

-search the click archives using google e.g. 'configuration
